<p>Abandonment of agricultural land during urban development reduces land use efficiency, land quality, and urban aesthetics. It is affected by many different factors. Until now, there has been no research to determine all the factors influencing agricultural land abandonment and their influence levels. So, the study's primary purpose is to evaluate the current state of agricultural land abandonment and the level of simultaneous impact of different factors on it during urban development. The study randomly investigated 255 households abandoning agricultural land about the factors causing that phenomenon by two steps. The hypothesized model of factors was tested through evaluation criteria. Research results have shown for the first time that agricultural land abandonment is affected by 7 factor groups. Their impact rate ranges from 5.21% to 26.61%. The land factor group has the most substantial impact; Officials and civil servants have the slightest effect. Proposed solutions to reduce agricultural land abandonment and use it more efficiently include converting low-yield agricultural land to non-agricultural land, ensuring infrastructure for agricultural land use, providing financial support, livestock, and seedlings to farmers during production, and encouraging farmers to rent land when they are not using it.</p>
